SPECIFICATION forming part of Letters Patent No. 333,823, dated January5, 1886,

Application filed September 29, 1885.

Serial No.178,534. (No model.) Patented in England May 2-2, 1885, No.6,307.

To all whom, it may concern:

Be it known that I, GEORGE BRAY, a subject of the Queen of Great Britainand Ireland, and residing at Blackman Lane, Leeds, in the county ofYork, England, have invented certain new and useful Improvements in Gas-Regulators, of which the following is a specification.

My invention consists of certain improvements in that class ofgas-regulators which are to be applied to gas pipes or mains to regulatethe flow of gas, and to prevent the pulsations caused by the working ofgas-engines or similar devices from affecting the pressure, as morefully described hereinafter.

In the accompanying drawings, Figure l is a side view, partly insection. Fig. 2 is a view at right angles thereto, and also partly insection. Fig. 3 is a section on the line 1 2, Fig. 1; and Figs. 4 and 5illustrate, in sections at right angles to each other, a modified formof valve.

The valve-case A is in communication with the gas-service pipe B comingfrom the main, and is immovable by being attached to an immovable partof the bag or reservoir, or otherwise. As shown in the drawings, it isattached to the pipe 13 and the part 0, which forms one of the ends ofthe expanding and contracting bag, bellows, or reservoir 0. The case Ais divided, along its whole length, into two compartments,A A by aplate, a,in which is a long slit, to. One of these compartments (that A)is closed at both ends, and the other (that A is closed at the outerend, and in the other end of this second compartment the valve D works,and from this end of this second compartment the gas is supplied to thebag or reservoir. The gas passes into the bag or reservoir through theaforesaid slit a when the valve D does not close it. The area of theslit, when fully open, is large enough to pass an ample supply of gasfor the engine or other consumer.

To the valve D is attached a spindle, d, connecting it with a movablepart of the bag or reservoir. It is shown in the drawings as beingattached to the cover 0 of a tube, 0', on the movable end of the bag orbellows 0, this tube allowing of the bellows closing, theinternallyprojecting part of the casing A entering this tance withoutmoving the valve.

tube 0". Owing to the gas entering the bag or reservoir 0 the valve D isdrawn forward in its compartment A of the case, thereby reducing thearea of the slit a, through which the gas can enter the bag orreservoir.

I prefer to time the closing of the valve D so that it takes placebefore the pressure of the gas inside the bag or reservoir exceeds thatof the surrounding atmosphere, except to the small extent required toopen the bag or reservoir, and this whatever may be the pressure in theservice pipe and main.

By thus supplying the engine or other consumer with gas at apractically-constant pressure I secure a regularity of charge, andthereby prevent waste and irregularity in the working of the engine orother apparatus, and to a great extent reduce the jumping of the lightson the same main due to the variation of pressure resulting from takingin the charges of gas from the bag or reservoir. Some variation ofpressure, and consequent jumping of lights, would be caused by the valveD moving as often and to the same extent as the movable end of the bagor reservoir; but to prevent this I make the spindle d of the valvecapable of a certain amount of movement independently of the valve,which may be effected by passing the spindle loosely into or through thevalve and fixing on the said spindle two stoppers, 01 and d so arrangedthat the spindle can be moved backward and forward for some dis- By thismeans, when the quantity of gas taken into or out of the bag orreservoiris not being greatly varied by the requirements of thegas-engine or other consumer, the pulsations of the bag or reservoiroccur without moving the valve, and consequently without disturbing thegas in the service pipe and main.

The valve-case A may be attached to the service-pipe and to the bag orreservoir in a similar manner to the valve-case, shown in Fig. 1. On theupper side of the interior of the valve-case there is the channel a forthe gas, the said channel extending from the servicepipe to near theoutlet end of the case, which passes into the bag or reservoir. The partof the valve D next the inside of the bag or reservoir is conical, andthe other end of the valve fits the interior of the valve-case, and issufficiently heavy to balance the conical end of the Valve. The valve isconnected to the movable end of the bag or reservoir, and is moved in asimilar way to that hereinbefore described. As the valve is drawnforward, its thick-end gradually closes the gasway, and when it ispushed back the gasway is gradually widened.

The gas is supplied to the engine or other consumer from the bag orreservoir through a pipe passing through the fixed end of the bag orreservoir in any convenient position, but by preference below thevalve-case.

In the drawings I have shown atE the pipe for the withdrawal of the gasfrom the bag 0, which bag I have shown as provided with a runner, F,mounted upon a rail or rod, f, eX- tending from the pipe B; but it is tobe understood that the details of construction can be greatly Variedwithout departing from the nature of my invention.

I claim 1. The combination of the collapsible reservoir of agas-regulator and gas-pipes with a casing having a narrow long slot anda sliding valve controlled by said collapsible reservoir.

2. The combination ofthe gas-pipes,and collapsible reservoir, and acasing having a long narrow slot, with a sliding valve connected to thecollapsible part of the reservoir, but leaving a play between the same,as and for the purpose set forth.

3. The combination of the gas-pipes and casing having an opening, and avalve adapted thereto, with a collapsible reservoir carrying a spindle,d, passing through said valve and provided with stops (1 and d Intestimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
